              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

                            (In Thousands of Dollars)


NOTE 1.    Earnings Per Share:

         Basic earnings per share is computed by dividing net income by the
         weighted-average number of shares outstanding. Diluted earnings per
         share is computed by dividing net income by the sum of the
         weighted-average number of shares outstanding plus the dilutive effect
         of shares issuable through the exercise of stock options.

         The components of the denominator for basic earnings per share and
         diluted earnings per share are reconciled as follows: (in thousands)

NOTE 2.    Comprehensive Income

         Effective April 1, 1998, the Company adopted Statement of Financial
         Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income."
         This statement requires that the Company report the change in its net
         assets during the period from nonowner sources. This statement only
         requires additional disclosures, and does not impact the Company's
         consolidated financial position or cash flows. For the three and six
         month periods ended September 27, 1998 and September 28, 1997, other
         comprehensive income is comprised of foreign currency translation
         adjustments and unrealized holding gains/(losses) on marketable
         securities. Comprehensive income is summarized below.

</TABLE>

         Credit Agreement

         Effective July 24, 1998, the Company's revolving credit line ("the
         Revolver") was revised and amended to increase the Revolver to $125
         million and eliminate Term Loan A and Term Loan B. The new credit
         agreement is substantially with the same group of lenders and has
         similar collateral and customary financial covenants, but is no longer
         asset based, and does not require principal payments until maturity on
         July 23, 2003.

         On September 27, 1998 the Company's domestic debt consisted of $90.6
         million of borrowings under the Revolver and $0.7 million of other
         borrowings. Letters of credit outstanding under the line at September
         27, 1998 were $0.1 million. Amounts outstanding under International
         Lines of Credit were $21.7 million at September 27, 1998.

         Other

         Other long-term debt is comprised principally of an obligation due
         under a collateralized borrowing arrangement with a fixed interest rate
         of 3% due December 2004 and loans on life insurance policies owned by
         the Company with a fixed interest rate of 5%.


NOTE 6.    New Accounting Pronouncements Not Yet Adopted

         In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
         of an Enterprise and Related Information", which will be effective for
         the Company's current fiscal year. SFAS No. 131 redefines how operating
         segments are determined and requires expanded quantitative and
         qualitative disclosures relating to the Company's operating segments.
         The Company is currently evaluating which operating segments, if any,
         it will disclose differently than previously reported.

         In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
         about Pensions and Other Postretirement Benefits - an amendment of FASB
         Statements No. 87, 88 and 106." This statement, which will be effective
         for the Company's current fiscal year, requires revised disclosures
         about pension and other postretirement benefit plans. The adoption of
         this statement will not have any impact on the Company's consolidated
         financial position, results of operations or cash flows.

         In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and
         Hedging Activities," was issued and is effective for the Company for
         its fiscal year ending March 31, 2001. SFAS No. 133 requires that all
         derivative instruments be measured at fair value and recognized in the
         balance sheet as either assets or liabilities. The Company is currently
         evaluating the impact this pronouncement will have on its consolidated
         financial statements.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
           RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

All references to three and six month periods in this Management's Discussion
refer to the three and six month periods ended September 27, 1998 for fiscal
year 1999 and the three and six month periods ended September 28, 1997 for
fiscal year 1998. Also when referred to herein, operating profit means net sales
less operating expenses, without deduction for general corporate expenses,
interest and income taxes. Unless otherwise indicated, amount per share refers
to diluted amounts per share.

Sales from continuing operations for the six month period in 1999 were $107.9
million, an increase of $7.9 million or 8% from the comparable period in 1998.
For the three month period in 1999 sales were $56.4 million, a $6.4 million or
13% increase from the comparable period in 1998. As further discussed below, the
increased sales performance for the six and three month periods in 1999 resulted
primarily from the acquisitions of ARM on June 29, 1998 and NORCO, Inc. on July
28, 1998.

Gross profit for the six month period in 1999 increased $3.6 million or 11% from
the comparable period in 1998. For the three month period in 1999, gross profit
increased $2.0 million or 13%. Operating profit from continuing operations for
the six month period in 1999 was $18.1 million, an increase of $1.9 million or
12% from the comparable period in 1998. For the three month period in 1999
operating profit from continuing operations was $8.8 million, an increase of
$0.7 million or 9% from the comparable period in 1998. Changes in sales,
operating profit and new orders from continuing operations are discussed below
by segment.

Net income, after an extraordinary item for the six month period in 1999 was
$4.6 million or $0.72 per share, compared to $4.5 million or $0.87 per share,
for the comparable period of 1998. The three month period in 1999 reported net
income of $1.4 million or $0.22 per share after the extraordinary item, compared
to $2.3 million or $0.43 per share for the year earlier period. Net income for
both the six month and three month periods in 1999 includes an extraordinary
charge in the amount of $0.8 million or $0.12 per share after tax for the
refinancing of debt. Net income for both periods also includes the establishment
of a $1.2 million pretax allowance for a possible loss on a note receivable from
the sale of a previously discontinued company. The extraordinary charge for the
refinancing of debt is discussed in more detail in the discussion of liquidity
and capital resources section.

Interest expense decreased $0.9 million and $0.3 million for the six month and
three month periods in 1999, respectively. The decreases were primarily the
result of reduced bank debt following the November 1997 common stock offering.
These proceeds were subsequently used for acquisitions during the second quarter
of fiscal 1999 as discussed in Note 4.


                                       10
<PAGE>   12
New orders received during the six month period in 1999 totaled $112.4 million,
an increase of $11.2 million or 11% from 1998's comparable period. For the three
month period, new orders totaled $61.9 million, an increase of $12.5 million or
25% from last year's comparable period. The increased new orders for both the
six month and three month periods were primarily due to the acquisitions of ARM
and NORCO, Inc. as well as increased new orders at Breeze-Eastern and our
European operations. At September 27, 1998, total backlog of unfilled orders was
$101.6 million compared to $73.2 million at September 28, 1997, primarily due to
the acquisition of ARM and NORCO, Inc., as well as increased backlog at
Breeze-Eastern, Breeze Industrial, TCR and our European operations.

                                       13

SPECIALTY FASTENER PRODUCTS SEGMENT

Sales for the specialty fastener products segment were $87.4 million for the six
month period in 1999, an increase of $4.7 million or 6% from the comparable
period in 1998. Sales for the three month period in 1999 were up $3.6 million or
9% from the same period in 1998. The six and three month increases in 1999 were
primarily due to the inclusion of ARM's operations in the current year periods.
The increased sales from the ARM acquisition were partially offset in both
periods by lower domestic retaining ring sales relating to the consolidation of
our two North American retaining ring factories. International fastener sales
for both periods were slightly higher with an increase in European sales
partially offset by a decrease in Brazilian sales.

Operating profit for the segment was $13.4 million for the six month period in
1999, an increase of $1.0 million or 8% from the comparable period in 1998. The
three month period in 1999 reported an operating profit of $6.5 million, an
increase of $0.2 million or 3% from the comparable period in 1998. The increased
operating profit was mainly due to the ARM acquisition partially offset by
decreased operating profit due primarily to overhead absorption issues arising
from the consolidation of our North American retaining ring factories.

New orders increased by $2.8 million or 3% for the six month period in 1999, as
compared to the six month period in 1998. New orders for the three month period
in 1999 increased $0.5 million or 1% from the comparable period in 1998. The
primary reason for these increases was the acquisition of ARM and increased new
orders at our European operations. Backlog of unfilled orders at September 27,
1998 was $52.6 million compared to $41.5 million at September 28, 1997,
primarily due to the acquisition of ARM and increased backlog at Breeze
Industrial, TCR and our European operations.

AEROSPACE PRODUCTS SEGMENT

Sales for the aerospace products segment were $20.5 million for the six month
period in 1999, an increase of $3.2 million or 19% from the comparable period in
1998. Sales for the three month period in 1999 were $11.2 million, up $2.8
million or 32% from the comparable period in 1998. The increases were primarily
due to the acquisition of NORCO, Inc.

Operating profit for the six month period in 1999 was $4.7 million, an increase
of $0.9 million or 25% from the comparable period in 1998. The three month
period had an operating profit of $2.3 million, an increase of $0.5 million or
30% from the comparable period in 1998. The increased operating profit for both
periods was primarily due to the acquisition of NORCO, Inc.

New orders for the six month period in 1999 increased $8.4 million or 51% from
the comparable period in 1998. New orders for the three month period in 1998
increased $12.0 million or 167% from the comparable period in 1998. The
increases in both 1999 periods were due to the NORCO, Inc. acquisition as well
as a large increase at Breeze-Eastern, primarily due to customer timing and
placement of new orders. Backlog of unfilled orders at September 27, 1998 was
$49.0 million compared to $31.8 million at September 28, 1997, primarily due to
the NORCO, Inc. acquisition and higher backlog at Breeze-Eastern.

LIQUIDITY AND CAPITAL RESOURCES

The Company's debt-to-capitalization ratio was 49% as of September 27, 1998,
compared to 35% as of March 31, 1998, primarily due to increased bank borrowings
for the acquisitions of ARM and NORCO, Inc. in the second quarter of fiscal
1999. The current ratio at September 27, 1998, stood at 2.82 compared to 2.17 at
March 31, 1998. Working Capital was $69.0 million at September 27, 1998, up
$12.6 million from March 31, 1998.

During the six months ended September 27, 1998 the Company purchased 60,000
shares of treasury stock for $1.4 million. Treasury stock purchases are made in
the open market or in negotiated transactions when opportunities arise. Plans to
purchase Treasury stock are subject to the terms of the Company's credit
agreement and may be discontinued by the Company at any time.

On June 28, 1998, the Company reclassified approximately $5.4 million of assets
held for sale, primarily land and buildings, to other long term assets due to
the termination of sales negotiations. There are no current substantive
negotiations which could result in liquidation within the next twelve months,
although the Company continues to actively seek to sell the properties.

Management believes that the Company's anticipated cash flow from operations,
combined with the bank credit described above, will be sufficient to support
working capital requirements, capital expenditures and dividend payments at
their current or expected levels. Capital expenditures in the six month period
in 1999 were $5.1 million as compared with $3.2 million in the comparable period
in 1998.

EXTRAORDINARY CHARGE FOR REFINANCING OF DEBT

On July 24, 1998 the Company refinanced its long term debt. The new financing
agreement increased the Company's revolving credit limit to $125 million and
eliminated the Term A loan and the Term B loan. The new agreement is with
substantially the same group of lenders and has similar collateral and customary
covenants, but is no longer asset based and does not require principal payments
until maturity on July 23, 2003. Due to the termination of the old credit
agreement, the Company took a charge to earnings in the current period to write
off the unamortized portion of the loan origination costs associated with the
old agreement in the amount of $1.2 million before tax or $0.8 million after
tax. The after tax amount of $0.8 million is classified as an extraordinary
charge in the Statement of Consolidated Operations for the three month and six
month periods ended September 27, 1998.

YEAR 2000 ISSUE

The Company has recognized the year 2000 issue which relates to the computer
storage of dates with the format of the year as either a two digit or a four
digit data field. Computer programs which have only a two digit field for the
year must be modified prior to the year 2000 otherwise the year 2000 may be
confused with year 1900.


                                       15
<PAGE>   17
The Company has taken steps to have all of its computer systems in compliance
with the year 2000 date requirement before that date is reached. Thus far the
Company has reviewed its internal computer systems at all locations for
compliance. Identification and testing of all internal systems has been underway
for the past year and is in the later stages of completion. Progress is
currently being monitored on a monthly basis at all business units. Some surveys
of key customers and suppliers have been obtained and are being updated on an
on-going basis. Based on the information obtained to date, the Company does not
believe there will be any significant interruptions in systems that will
adversely affect the company relative to the year 2000 issue. The Company is not
able however to identify all external year 2000 issues such as those which may
exist at the governmental, supplier and customer levels.

The Company's planned expenditure for year 2000 compliance is $0.5 million, most
of which has been or is expected to be spent during the current fiscal year. The
Company has addressed contingency planning for the year 2000 issue and has
outlined various plans for further development based upon additional test
results and survey findings. The anticipated completion date for all Year 2000
compliance is September 1999.
